?2-channel isolated barrier ?24 V DC supply (Power Rail)
?TC, RTD, potentiometer or voltage input ?Current output 0/4mA...20mA ?Sink or source mode
?Configurable by PACT ware ]TM
?Line fault (LFD) and sensor burnout detection ?
Up to SIL2 acc.to IEC 61508/IEC 61511
Function
This isolated barrier is used for intrinsic safety applications. It is designed to connect RTDs, thermocouples, or potentiometers in the hazardous area, and provide a proportional 0/4mA ...20mA signal to the safe area.The barrier offers 3-port isolation between input, output, and power supply.
A removable terminal block K-CJC-** is available for
thermocouples when internal cold junction compensation is desired.
A fault is indicated by a red flashing LED per NAMUR NE44 and user-configured fault outputs.
The unit is easily programmed with the PACT ware ? configuration software.
A collective error messaging feature is available when used with the Power Rail system.

Power feed module KFD2-EB2
The power feed module is used to supply the devices with 24V DC via the Power Rail. The fuse-protected power feed module can supply up to 100 individual devices depending on the power consumption of the devices. A galvanically isolated mechanical contact uses the Power Rail to transmit collective error messages.Power Rail UPR-03
The Power Rail UPR-03 is a complete unit consisting of the electrical inset and an aluminium profile rail 35mm x 15mm. To make electrical contact, the devices are simply engaged.Profile Rail K-DUCT with Power Rail
The profile rail K-DUCT is an aluminum profile rail with Power Rail insert and two integral cable ducts for system and field cables. Due to this assembly no additional cable guides are necessary.
Power Rail and Profile Rail must not be fed via the device terminals of the individual devices!
K-CJC-**
This removable terminal block with integrated temperature measurement sensor is needed for internal cold junction compensation for thermocouples. One K-CJC-** is needed for each channel.PACT ware ?
